By default, OpenJPA's postgres dictionary generates VARCHAR(255) for String fields without stated length. Can it be set up to generate VARCHAR or TEXT instead for all such fields, so that I don't need to repeat @Column(columnDefinition = "TEXT") everywhere? Of course, if the length is given explicitly, e.g. @Column(length = 128), the result should be VARCHAR(128). For that matter, do any other JPA providers allow this?
It seems that Hibernate supports this since 3.6: 6.5. Type Registry. Tracked by this JIRA issue: HHH-5138.
